I haven't had the problem that Beidao describes, but I do find that there are some times I simply can't connect with TeaChat at all.
For example, I was working through some threads this morning when, somewhere between 10:15 or 10:30 Pacific (can't recall the exact time), the TeaChat site stopped responding. I couldn't post to the thread I was in, and I couldn't even open the homepage. The site was unavailable (as far as I was concerned) for the next half hour or so - I periodically checked it as I visited some other sites, which did work just fine - and finally I gave up and stopped trying. This post represents my first attempt since lunchtime.
This has happened several times before. Am I the only person experiencing these outages, or is this a site issue, or...?
